Toll-like receptors (TLRs) play critical roles in triggering immune and inflammatory responses by detecting invading microbial pathogens and endogenous danger signals. Increased expression of TLR4 is implicated in aggravated inflammatory symptoms in ischemic tissue injury and chronic diseases. Results from our previous study showed that TLR4 expression was(More)
Toll-like receptors (TLRs) are germline-encoded innate immune receptors that recognize invading micro-organisms and induce immune and inflammatory responses. Deregulation of TLRs is known to be closely linked to various immune disorders and inflammatory diseases. Cells at sites of inflammation are exposed to hypoxic stress, which further aggravates(More)
Toll/IL-1R domain-containing adaptor inducing IFN-β (TRIF) is an adaptor molecule that is recruited to TLR3 and -4 upon agonist stimulation and triggers activation of IFN regulatory factor 3 (IRF3) and expression of type 1 IFNs, which are critical for cellular antiviral responses. We show that Akt is a downstream molecule of TRIF/TANK-binding kinase 1(More)
Activation of Toll-like receptor 4 (TLR4) triggers immune and inflammatory events by sensing endogenous danger signals as well as invading pathogens and contributes to the development of chronic inflammatory diseases. In this study, we investigated effect of 1-palmitoyl-2-(5-keto-6-octenedioyl)-sn-glycero-3-phosphocholine (KOdiA-PC), an oxidized(More)
TLRs are pattern recognition receptors that detect invading microorganisms and nonmicrobial endogenous molecules to trigger immune and inflammatory responses during host defense and tissue repair. TLR activity is closely linked to the risk of many inflammatory diseases and immune disorders. Therefore, TLR signaling pathways can provide efficient therapeutic(More)
